I am experiencing a similar issue except I can't get PORT level information on the edge. I can see the NNI to my 8404 and I can see the MAC and IP on the core but NOTHING at the edge, I can tell you what port on my core it plugs into.
I have a ERS4950 GTS PWR+ and I am having no issues whatsoever, I can see the edge port along with the device MAC, DNS, and IP address.
So my 4800s I get nothing on the edge port, my 4900s I get everything on the edge port.
My cores I can see everything on both of them.
